Schema history: reverts run only against the current database, snapshot the live
schema first and refuse on drift, and a catch-up plan is no longer reported as
destroying data. Clicking a graph node highlights it and its lineage.

Utilities: PostgreSQL index fragmentation uses pgstatindex (pgstattuple has no
leaf_fragmentation column, so the probe never worked); MariaDB is its own family
rather than a MySQL alias, fixing System info and the blank connection counts.

SQLite and DuckDB credentials show a file path instead of host/port/user/password,
with a server-side file picker, and are selectable again as Source or Target.
